LOOM-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 237,682, dated February 15, 1881. Application filed September 14,1880. (N 0 model.)

To all whom it may concern.-

Be it known that I, JAMES HAMILTON, a citizen of the United States, residing in Great Falls, Strafl'ord county, New Hampshire, have invented an Improvement in Loom shuttles, of which the following is a specification.

My invention relates to the construction and application to a shuttle of a spring for acting on the butt of the spindle, the object of my invention being the construction of the spring for ready and economical application to a recess in the shuttle-body and the securing of the spring in its place withoutthe aid of screws or pins.

In the accompanying drawings, Figure 1 is a longitudinal view of the improved shuttle, showing the body in section and spindle and spring in elevation; Fig. 2, a plan view of the shuttle; Fig. 3, a section of part of the same, showing the manner of inserting the spring into its place in the shuttle-body; and Figs. 4 and 5, views of different kinds of my improved springs.

The body A of the shuttle may be of the usual form, and the spindle may be of any style, providing it has a projection, a, at the butt for the spring to bear against, and a projection, b, to bear against the body of the shuttle when the said spindle is depressed. The slot 01, which is cut in the shuttle-body for the reception of the butt of the spindle, is continued for a short distance toward the end of the said body, and terminates in and communicates with a deep recess, 6, one side of this recess being notched at f and the opposite side notched at h.

The spring 1) consists of a flat strip of metal-steel or iroubent and folded to the form shown, so as to have a projection, t, adapted to the notch him the recess 0, near the upper end of the same, and a projection, m, adapted to the notch f in the opposite end of the recess,near the bottom thereof,part of the strip forming the tongue n, which bears upon the projection aon the buttof the spindle. This spring must be introduced into its place in the shuttle-body before the spindle B is applied to the same, the spring being first adjusted to the position shown in Fig. 3, after which the tongue n is raised and the butt of the spindle 5o forced to its place in the recess, so that its projections shall enter their respective notches. The butt of the spindle is then introduced into the slot in the body of the shuttle, and the pin q passed through the body of the spindle and eye of the said butt. After the spindle is in its place the spring is securely held, and cannot be removed without first'detaching the said spindle.

The spring, Fig. 4, is used when a cop is ap- 6o plied to the spindle, and the spring, Fig. 5,. when a bobbin is used in connection with the shuttle, the latter spring being exactly like the former, as far as concerns the mode of connection to the shuttle-body, but having a lip, w, for entering the groove of the bobbin.

The spring, being held in its place independently of the usual screws or pins, is more securely retained than usual, and'is stronger than an ordinary spring, as it is not weakened by the formation of screw-holes in it.

I claim as my invention 1. The combination of the spindle and its butt and the body of the shuttle having a recess, 6, with the spring D, adapted to said recess e, and having two bearings, i and m, therein, as set forth.

2. The combination of the spindle and its butt, the body of the shuttle having a recess,

e, with notches fand h, and a spring, D, hav- 8o ing projections z and m, adapted to the said notches, all substantially as described.

3. The within-described spring, consisting of aflat strip of metal bent to the shape shown and described, so as to form projections 11 and 8 5 m, and being otherwise constructed for application to a notched recess in a shuttle-body, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two 0 subscribing witnesses.

JAMES HAMILTON.
